To all whom it concern.-

Be a known that I, LEON P. LOWE, a'citi- 'zeii of the United States, residin at San Franclsco, 1n the county of San Apparatus, of which the following is a specificatlon.

My invention relates to an improved apfiaio ratus for manufacturing gas, and es ecia ly is a broken plan view.

Referring to the drawings, 1 represents an 2 L-shaped casing lined with refracto material 2. The upright member is divided by arches 3 into u per and lower chambers 4 and 5, said arches bein spaced fi'cuieach'other, as shown in dotted 'nes at 6 fii'Flg. 2, to per- 301ml? the gases to pass between the two chamhere. In saidchambers 4 and 5 are piles of refractory material 7 8. The lower pile 8 of refractory material is en ported by arches 9 above a chamber 10, which communicates 5 with a combustion and coking chamber 11 over a wall 12, extending transversely near the end of said chamber 11 next to said chamber 10, the to of said wall being arched, as shown, and approaching closely to the arched 4o roof of said combustion and coking chamber.

13 is a jet-exhauster located upon the top .of the combustion-chamber over the arched Wall, leading to the auxiliary flue 14. 4 15 is the main flue, leading to the stack 28 and controlled by a valve 18.

16 is an oil-inlet for su plying oil for combustion to be burned at t e top of said combustion and coking chamber.

17 is a steam-pi e at the top of the chamher 4; 19, an oil-1n et at the top of the chamher 5, 27 being a steam-supply pipe for injecting said oil, and 20 a gas-outlet.

21 is the doorfor the coking-chamber.

22 is a valve on the top of the jet-exhauster 13. r

The 0 eration of'the apparatus is as.f0l lows: O1 is admitted into the combustion- 23 is an air-sipply pipe conducting to the chamber through the oil-supply 16 and-is burned therein, the products of combustion passing through the chambers 5 4,and thor-,- oughly heating the efractory material therem and escaping up theflue 15.

The steam is thus t oroughly superheated, and the oil ander.- heated steam passing through the piles 0 refractory material in the chamber 5 are disas-, sociated and recombine as carbon monox1d,

" The apparatus is also used for the following purposes: The tarry and carbonaceous resi' dues from gas-making'have heretofore been used for feeding furnaces; but the following is a more economical way of utilizing the same.

Said residues are collected and placed in the 1portion ofthe coking-chamber 11', throug the door 21, and when the oil is burned in the upper portion of said chamber for heating the piles of refractory material the residues are coked by the radiant heat 1 from the arch of the coking-chamber and also by the gases arisin during the heating of said residues, as n-the .eehive process of making coke from bituminous coal. The gas thus formed is burned to assist in the heating of the 29 refractory material during the heating part of the o I voration, and during the gas-making part t d a ereof it is recovered an ded to the other manufactured gases. Evidently this utilization of these'residues is more eonomi c al than that heretofore made:
